1 Introduction
The MC300 is a general-purpose power stage board able to drive brushless DC,
brushed DC and stepper motors. The board is designed to be a flexible platform for
developing motor control applications. Power and all signals needed for a controller
(AVR
®
CPU) are available on the left side of the board, giving a modular system
where boards with different microcontrollers can easily be connected.
